N/A

• Scroll Compressors on all models: Provides maximum efficiency and quiet operation.
• MicroChannel Evaporator and Condenser Coil: Delivers superior performance with less refrigerant charge and less weight than conventional copper tube/aluminum fin coils. All aluminum construction has superior protection against formicary corrosion and aluminum tube rubbing potential. It is easier to clean and has a more robust surface.
• Thermal Expansion Valves: Standard on all models for precise superheat control, reliability, and energy efficiency at all operating conditions.
• High Pressure Control: Standard on all models for refrigerant component protection and reliability.
• Filter Drier: Standard on all models.
• 100% Factory Run Tested.
• PlusOne® Refrigerant Detection System™: An integrated one-box, patented design featuring the A2L sensor and mitigation board, offering easier commissioning with a single component and simplified wiring configuration, compatibility with any 24V thermostat application and system protection by automatically pausing outdoor unit operation – if excess refrigerant is detected.
• Metal Base Rails: Allow for separation between the unit base and the ground level, protecting the base from ground moisture and providing air circulation around the unit. It also allows for easier maneuverability during installation. To provide flexibility in space limited installations, the unit can be installed flush to the structure without blocking airflow over the outdoor coil or making any screws inaccessible for maintenance.
• Two Round 14" Duct Collars: Included with each unit. The collar is crimped around the leading edge, making it easier to install duct onto the collar. A metal bead around the circumference prevents the attached ducting form sliding off after installation.
• Easy High and Low Refrigerant Pressure Measurement: Two gauge ports located inside the control box allow for ease and accuracy.
• Removable Sloped Drain Pan: Accessible through a small side panel. Helps to ensure indoor air quality (IAQ) throughout the life of the unit.
• Closed-Cell Insulation: Used on the base of the unit, to prevent moisture from being absorbed and helps reduce mold content.
• Louvered Condenser Compartment: Protects the coil against yard hazards and/or weather extremes.
• Easily Removable Outdoor and Indoor Section Top Cover: Allows access to the compressor, refrigerant tubing, blower housing and motors for easy required cleaning and service.
• Easy Access Control Box: Controls are in the large control box and provides plenty of space in which to troubleshoot.
  — Demand defrost control is used to manage the defrost cycle
  — Transformer is protected by an in-line fuse, which protects the transformer during a low-voltage electrical short
  — Low-voltage and high-voltage wiring connections are easily accessed and have ample room to maneuver
  — Number and color-coded wiring aids in troubleshooting and corresponds with the large, easy-to-read wiring diagram located on the inside of the control box access panel
• Factory and Field Installed Supplemental Electric Heat Strips: Available for periods of extreme cold temperatures with either dual or single-point power.
• Designing for Sustainability with Low GWP: For 2025, the Environmental Protection Agency (EPA) has set a global warming potential (GWP) limit of 700 for refrigerant used in heating and cooling systems. This new requirement will result in a 78%2 lower GWP than previous-generation refrigerants with only minimal changes to system installation. For us, this is another step toward our continued sustainability goal of reducing greenhouse gas emissions, while still delivering an exceptional level if energy efficient, dependable comfort.
